Scientists call on soda makers to limit caffeine

Australian scientists have called on soft drink manufacturers to implement tougher regulations on the use of caffeine, disputing claims that it improves taste.

The call was based on a study of the drinking habits of 99 participants across one month, which was conducted by scientists at Deakin University and published in the British Journal of Nutrition on Tuesday.

The participants were split into two groups, with one given caffeinated soft drinks to consume over the monthlong period and the other group supplied with non-caffeinated drinks.
